in my archive, I found this Trading System, and the author recommended to do tests with 3 Exit, to improve the efficiency and robustness of the T.S.
If someone could kindly transform the 3 Exit into Easylanguage and insert them into the formula, which I will try one at a time with the use of parentheses: { }.

These are the 3 Exit to be included in the formula; I will also turn them into: (after SellShort): Exit ....:

(after Buy): Exit with a profit after 30 bars, if the closing is less than the exponential moving average of 5 days.
(after Buy): Exit with a limit order if the open profit exceeds 20%.
(after Buy): Exit with a profit if the trade lasts for more than 50 bars.

This is the formula of the T.S. for Tradestation 8 or higher:

Hi,
yes, of course, also Sellshort (I would have done it , for not to disturb you too much).
Thank you very much.

------------------------------------------------

{after Buy}: Exit with a profit after 30 bars, if the closing is less than the exponential moving average of 5 days.
{after Sellshort}: Exit with a profit after 30 bars, if the closing is higher than the exponential moving average of 5 days.

{after Buy}: Exit with a limit order if the open profit exceeds 20%.
{after Sellshort}: Exit with a limit order if the open profit exceeds 20%.

{after Buy}: Exit with a profit if the trade lasts for more than 50 bars.
{after Sellshort}: Exit with a profit if the trade lasts for more than 50 bars.

{after Buy}: Exit with a profit after 30 bars, if the closing is less than the exponential moving average of 5 days.
What do you do your trade is profitable after 30 bars, but closing > mov avg 5 days?

{after Sellshort}: Exit with a profit after 30 bars, if the closing is higher than the exponential moving average of 5 days.

{after Buy}: Exit with a limit order if the open profit exceeds 20%.
You can use setprofittarget, but what is the 20%? 20% of what?

{after Sellshort}: Exit with a limit order if the open profit exceeds 20%.

{after Buy}: Exit with a profit if the trade lasts for more than 50 bars.
if marketposition = 1 and barssinceentry = 50 and close>entryprice then sell this bar at close; //market order
or
if marketposition = 1 and barssinceentry = 50 then sell next bar at entryprice limit; //limit order
And what are you going to do if the trade is not profitable after 50 bars?

{after Sellshort}: Exit with a profit if the trade lasts for more than 50 bars.

If it may be useful to someone, I insert here the 3 Exit translated in Esylanguage (thanks to Tom 1978):

If marketposition=1 and close>entryprice and barssinceentry=30 and close<xaverage(close,5) then Sell("LX 30") next bar at market;
If marketposition=-1 and close<entryprice and barssinceentry=30 and close>xaverage(close,5) then Buytocover("SX 30") next bar at market;

If marketposition=1 and close>1.20*Entryprice then Sell("LX target") this bar at close;
If marketposition=-1 and close<0.8*Entryprice then Buytocover("SX target") this bar at close;

If marketposition=1 and close>entryprice and barssinceentry=50 then Sell("LX 50") this bar at close;
If marketposition=-1 and close<entryprice and barssinceentry=50 then Buytocover("SX 50") this bar at close;

The following user says Thank You to Shaban for this post:

unfortunately the 3 Exits, allow the T.S. an over-optimization, because the T.S. always chooses the best solution.
An example: by inserting the Exit with a profit if the trade lasts more than 50 bar:

If marketposition=1 and close>entryprice and barssinceentry=50 then Sell("LX 50") this bar at close;
If marketposition=-1 and close<entryprice and barssinceentry=50 then Buytocover("SX 50") this bar at close;

the T.S. already before 50 bars will signal the Exit in profit, while subsequently, if the trend will continue beyond 50 bars, the T.S. will choose this last Exit, no longer signaling the previous Exit.
